Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options. 18 x minus 15 = 72 50 x minus 25 = 72 18 x minus 9 = 72 3 (6 x minus 3) = 72 x = 4.5

Answer:

x = 1

Step-by-step explanation:

Since all the fractions have a common denominator of 3, you can multiply both sides by 3 to get rid of the denominator. (Make sure you distribute)

[tex]\frac{7}{3}x+\frac{1}{3}x=1+\frac{5}{3}x[/tex]

[tex]3(\frac{7}{3}x+\frac{1}{3}x)=3(1+\frac{5}{3}x )[/tex]

7x + x = 3 + 5x

8x = 3 + 5x

8x - 5x = 3 + 5x - 5x

3x = 3

x = 3/3

x = 1

The compound interest would be Rs. 35835.51.

What is compound interest?

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

To calculate the total amount to be paid after 1.5 years at 15% p.a. compounded half-yearly, the formula is:

A = P(1 + r/n)^(nt)

Where:

A = total amount

P = principal amount (Rs 128000)

r = interest rate (15%)

n = number of times the interest is compounded per year (2 times per year)

t = number of years (1.5 years)

So, the total amount to be paid after 1.5 years would be:

A = 128000 * (1 + 0.15/2)^(2*1.5) = Rs 163835.51

The compound interest can be calculated by subtracting the principal amount from the total amount:

CI = A - P = 163835.51 - 128000 = Rs 35835.51

Hence, the compound interest would be Rs. 35835.51.

An estimate of the total number of televisions that would need repairing in Clover City is A. Between 546,000 and 972,000 televisions.

Thanks to the research by the local television repair shop, we know that on average, 2.53 ± 0.71 per family will need to be fixed.

The lower bound of this mean range would be:

= ( Mean - error ) x Number of households

= ( 2. 53 - 0. 71 ) x 300, 000

= 546, 000 televisions

The upper bound of the mean range is:

= ( 2. 53 + 0. 71 ) x 300, 000

= 972, 000 televisions

The estimate for televisions to be repaired is therefore between 546,000 and 972,000 televisions.

They made more than 1,000 sales per week for 26 weeks.

A sale is a transaction that involves exchanging products or services for a certain sum of money. To put it another way, a sale is any action that includes giving the buyer possession of a thing or commodity in return for payment.

The first sale is 15 units.

Sales are rising at a weekly rate of 18%.

1000 are the final sales.

The next week is when sales reach 1,000 or more:

[tex]1000=15 \times\left(1+\frac{18}{100}\right)^t \\\frac{1000}{15}=\left(\frac{118}{100}\right)^t \\\frac{200}{3}=(1.18)^t[/tex]

Solving further we get,

Within a yard, there are 36 inches (yd). In both the US customary and imperial systems of measurement, length is expressed in both inches and yards.In the United States, the United Kingdom, and its territories, these units are primarily used.

A man's belt or girdle, as it was referred as, measured a yard in length originally.King Henry I of England established the yard in the 12th century as being equal to the distance between his thumb and nose on his extended arm.

There are 36 inches today.

So, 313 yards = 11,268 inches.

There are 36 inches in one yard

You need to multiply 313 yards by 36 inches to get your answer,

To translate Geoff's order using Discrete Math,

2 ) Geoff is a truth-teller. Based on his last statement, where ricotta (R) is implied from pepperoni (P) or quail (Q) , we would have no way of knowing if R is true/false if (P or Q) was false- so, R must be true if (P or Q) is false because of the whole “innocent until proven guilty” thing. therefore, since a lie in P or Q would lead to truth, Geoff must be a truth-teller because he can’t tell all lies.

Using this information, that Geoff always tells the truth.

For the third statement, if Geoff is lying then the truth is "I must have pepperoni or quail and I cannot have ricotta cheese."

~[(P ∨ Q) → R] = [(P v Q) ∧ ~R)]

Or in more general terms, ~(a → b) = (a ∧ ~b)

Which, gives us (a → b) = (~a ∨ b)

Anyhow, even if Geoff tells all lies, there is a valid statement that can be made: Pepperoni and sausage, no quail, no ricotta.

There are 2 pounds of apples Hannah buy for the cost for her purchase to be the same from both stores.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

And, At Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Now,

Let number of pounds of apples can Hannah buy for the cost for her purchase to be the same from both stores = x

So, We can formulate;

For, At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

The total cost is,

⇒ $2.89 + $1.29x

And, For Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Total cost is,

⇒ $3.37 + $1.05x

Now, We can equate both the equation to find the number of pounds of apple to buy.

⇒ $3.37 + $1.05x = $2.89 + $1.29x

⇒ 3.37 + 1.05x = 2.89 + 1.29x

⇒ 3.37 - 2.89 = 1.29x - 1.05x

⇒ 0.48 = 0.24x

⇒ x = 0.48 / 0.24

⇒ x = 2

Answer:

This equation is Linear.

Step-by-step explanation:

You can use the Pythagorean Theorem to write an equation that describes how the side lengths are related as 20² + 15² = 25².

The Pythagorean theorem can be defined as a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.

Mathematically, Pythagorean's theorem is given by this mathematical expression:

a² + b² = c²

20² + 15² = 25².

400 + 225 = 625

625 = 625 (proof).

In conclusion, you would know that the geometric proof of the Pythagorean Theorem can be applied to all right triangles because the square of the hypotenuse is always equal to the sum of the square of the opposite side and the adjacent side of a right triangle.

The slop-intercept form of 2x + y = -2 is y = -2x - 2.

The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).

To convert the equation 2x + y = -2 into slope-intercept form, we can follow these steps:

1. Isolate y on one side of the equation. We can do this by subtracting 2x from both sides: y = -2x - 2

2. Now we have y = -2x - 2, which is in slope-intercept form.

So, the slope-intercept form of 2x + y = -2 is y = -2x - 2. The slope of the line is -2 and the y-intercept is (-2,0).

Therefore, the slope-intercept form of the equation 2x + y = -2 is y = -2x - 2.

Three equidistant dots on each of two parallel lines (see sketch for illustration purposes only) are joined in all possible ways. The number of triangles that can be formed is 20 triangles

A "Three equidistant dots" refers to three points that are evenly spaced apart on a line. These three points could represent the vertices of a triangle, and in this case, the question is asking how many triangles can be formed by connecting each of the three dots on one line to each of the three dots on a parallel line.

In total, there are 3 dots on one line and 3 dots on the other line, for a total of 6 dots, and the question is asking how many ways the dots can be connected to form triangles.

To find the number of triangles that can be formed, we use the formula for the number of combinations of n things taken 3 at a time, which is n! / (r!(n-r)!). In this case, n = 6 and r = 3.

The standard form of linear equation is written as ax + by = c, where a, b, and c are real numbers and a and b are not both zero.

In this form, the coefficients a and b are the slopes of the line and c is the y-intercept.

In the equation x = -5, the coefficient of x is 1 and the constant is -5. This equation can be written as 1x + 0y = -5, which is the standard form of the equation.

To solve this equation, we can first subtract 5 from both sides:

1x + 0y - 5 = -5 - 5

1x + 0y = 0

This is the simplest form of the equation and can be used to find the x-intercept of the line. By setting y = 0 and solving for x, we get x = 0. This means that the x-intercept of the line is (0, -5). We can also use this equation to find the slope of the line. The slope of the line is equal to the coefficient of x, which is 1.
